Uniform absolute continuity in spaces of set functions
Abstract: Let be a regular topological space, a collection of bounded regular measures defined on the Borel sets of . The following conditions are equivalent.
(1) Let denote the Borel measures, the nonnegative members of . There is a such that is uniformly -continuous.
(2) If is a disjoint sequence of open sets, then uniformly for .
(3) If is a Borel subset of and , there is a compact set such that for .
(4) If is a disjoint sequence of Borel sets, then uniformly for .
